I'm trying to upgrade my Ubuntu 18.04 LTS to Ubuntu 20.04 LTS. However, when I type in sudo apt update in the terminal, I get:

E: The repository 'http://ppa.launchpad.net/vikoadi/ppa/ubuntu bionic Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Is there any workaround for this?

I presume, you are using KDE or KDEconnect indicator application. The error is from said source, vikoadi. Remove the said source from the list for the timebeing and try the update again and you should use sudo apt update && sudo apt dist-upgrade. Make sure you have selected and opted for LTS versions in the software and update's update tab.
